pH+pOH=14. 如何计算pH值 pH值计算对于强酸和弱酸和碱,溶液的摩尔浓度值是不同的。 强酸和强碱 强酸和强碱是在正常情况下几乎完全在水中解离的化学物质。这意味着酸性溶液中氢离子的浓度可以取为等于酸的浓度。类似地,碱性溶液中氢氧根离子的浓度可以取为等于碱的浓度。
Finally, the pH can be found without a calculator if the hydroxide ion concentration is known. The following is understood: pH+ pOH = 14 We can use the known value of the pOH and subtract it from 14 to find the value of pH.pH...

Online pH and pOH calculator See the Resources for a web tool that allows you to determine the pH of various acidic and basic solutions. You can use this to gain a feel for the relationships between different individual acid strengths, concentration and pH. References OpenStax Mathematics for ...
Acid Base Equations pH = -log [H3O+] [H3O+] = 10^(-pH) pOH = -log [OH-] [OH-] = 10^(-pOH) pH + pOH = 14 [H3O+] [OH-] = 1 x 10-14 Sig Figs and pH The number of decimal places in the log value, pH value, is equal to the number of significant figures in the ...
How can the pH of a solution be calculated if the pOH is known? What is the relationship between pH and the reaction rate? Convert each H3O+ concentration to a pH value. 9.3 x 10^-4 M and 9.48 x 10^-9 M. A solution has a H+ = 3.1 x 10-4 M. Determine the pH, pOH and ...
Determine the pH, pOH and indicate if the solution is acidic, neutral or basic. When given the pH of a substance and no calculator is available, is there an easy way to mentally do the math to find the H^+ or OH^- concentrations? How about the other way aro...
\(\begin{array}{l}\Rightarrow pOH = pK_b + log~\frac{[BH^+]}{[B]}\end{array} \) Important Points to Remember When exactly half of the acid undergoes dissociation, the value of [A]/[HA] becomes 1, implying that the pKaof the acid is equal to the pH of the solution at this...
I see your calculator required 17 iterations. I don't remember claiming any end result as inadequate. But I am also conscious of the length of the path yet to be trod. I am just trying to build up from small beginnings in simple steps. The issue is really not one of "is the model...
